Question

what is the term for a person who shows no sign of illness but has pathogenic bacteria living on their skin, scalp, or inside their nose?
colonized
infected
carrier
none of the above

Explanation:

A carrier is an individual who harbors pathogenic bacteria without showing symptoms of illness. Colonized refers to the presence of bacteria on a surface without necessarily causing disease, but it doesn't imply the person is symptom - free. Infected means the person has an active disease. Since the question asks for a person with no illness symptoms but pathogenic bacteria, carrier is the correct term.

Answer:

Carrier
